Answer: 27
Step-by-step explanation:
3(2c+3)
If c=3, then the equation can be written as: 3(2(3)+3)
You would multiply 2 and 3 first
=3(6+3)
And then do distributive property
=18+9
Combine terms
= 27
Answer:
Step-by-step explanation:
Converting celsius to farenheit
C * 1.8 + 32
220 * 1.8 + 32 = 396 + 32 = 428 F....so 220 C = 428 F
so he set the oven for 428 F, when it was supposed to be set for 400 F
428 - 400 = 28.....28 degrees too hot
